2+cos^2(x)=3cos(x)

2 + cos^{2} (x) = 3 cos (x)

x = 2 πn

Solution steps

2 + cos^{2} (x) = 3 cos (x)

Solve by substitution

cos (x) = 2, cos (x) = 1

cos (x) = 2 :

No Solution

cos (x) = 1 : x = 2 πn

Combine all the solutions

x = 2 πn

cos (x + 4 0^{\circ}) = 0.85

sin^{2} (a) = 1 - cos (2 a)

cos^{4} (x) = cos^{2} (x)

tan (x) = 2 + tan^{3} (x)

2 \cdot sin (a) = sin (3 a)
